LSD直线检测说明文档，很详细，非常具有参考价值-LSD line detection documentation, very detailed, very valuable reference

We propose a linear-time line segment detector that gives accurate results, a controlled number of false detections, and requires no parameter tuning. This algorithm is tested and compared to state-of-the-art algorithms on a wide set of natural ima
